What is the price of Experience? do man buy it for a song?
Or wisdom for a dance in the street? No, it is bought with the price
Of all that a man hath, his house, his wife, his children.
Wisdom is sold in the desolate market where none come to buy,
And in the wither'd field where farmer plows for bread in vain.
- Blake, Vala or The Four Zoas
